J OHN F. HEMENWAY, OF NEW YORK N. Y.

GLOTHES-WRINGER.

' Specification of Letters Patent.

Patented Nov. 21, 1916.

Application filed April 1, 1916. Seria1No.'88,246.

To all whom it may concern Be it known that I, JOHN F. HEMENWAY, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Clothes-Wringers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and .useful improvements in clothes wringers,

and more particularly to a pressure roll releasing device for releasing the pressure on the pressure rolls in case of an accident, the object being to provide an exceedingly s1mple and cheap releasing device which can be well known form of Wringers now in use.

Another object of my invention is to pro vide a pressure roll release in which the top bar carrying the pressure screws is held in position within the side bars of the wringer frame by the cross bars of a bowed spring so that when the spring is elongated, the

top bar of the frame will be free to move vertically to release the pressure on the pressure roll.

Other and further objects and advantages of the invention will be hereinafter setforth' and the novel features'thereof definedby In the drawing, Figure 1 is a side elevation of a clothes wringer partly in section showing my improved construction of pressure roll releasing device applied thereto.

Fig. 2 is a top plan view showing the formation of the spring, and Fig.3 isan end elevation. I 1

Like numerals of reference refer to like parts in the several figures of the drawing. In the drawingyl and 2 indicate the side bars of a wringer frame which are connected together adjacent their lower ends by cross bars 3. The side bars are rovided with slotted upper portions in whicli are mounted bearings 4 and 5 carrying shafts 6 and 7 provided with pressure rolls 8 and 9, the lower shaft 7 being provided with suitable means for driving the same, not shown.

Mounted on the upper bearings 5 of the upper pressure roll is a cross bar 10, the ends of which are slidably mounted within the slotted portions of the side bars 1 and 2 and upon which rest the free ends of a pressure spring 11 secured centrally to a pressure bar 12 which is slidably mounted within the slotted portions of the side bars 1 and and is provided with bearing plates 13, the purpose of which will be hereinafter fully described.

Arranged over the upper end portions of the side bars 1 and 2 are u-sbaped members 14 which are secured thereto in any suitable manner, the free ends of the U-shaped members extending inwardly as shown, and the upper edges of the U-shaped members are provided with hooks 15 and 16 adapted to receive the cross bars 17 and 18 and a bowed spring 19 herein shown formed of a single piece of wire bentto form enlarged portions at its ends, and provided with a central impact plate 20 which is adapted to be struck by the operator so as to elongate the a spring and throw the cross bars 17 and 18 from under the hooks 15 and 16.

Arranged within the slotted upper ends of the side bars 1 and 2 of the wringer frame is a top bar 21 which is provided with threaded boxes 22 adjacent its ends in which are mounted pressure screws 28, the lower ends of which engage the bearing plates 13 of the pressure bar 12 so as to adjust the pressure on the pressure rolls. The top bar is provided with substantially semi-circular bearing strips 24 adjacent each end arranged adjacent the hooks 15 and 16, and upon which the cross bars 17 and 18 of the spring 19 are adapted to normally rest when in position under the hooks 15 and 16 so that when the spring is struck a blow so as to elongate the same, a bearingwill be formed for the cross bars of the spring to insure the cross bars riding out from under the hook the movement of the ends of the springs.

The operation of the clothes wringer as herein shown and described in order to release the pressure on the pressure rolls in case of a foreign object being drawn between the pressure rolls, it is only necessary to strike the bowed spring 19 a blow so as to elongate the same and the, top bar will be released and allowed to move vertically, which in turn will release the pressure on the pressure bar, and as the pressure is released, the spring releases its pressure upon the cross bar mounted upon the bearings of the pressure rolls so as to allow the upper pressure roll to move vertically instantaneously.

I claim:

1. A clothes wringer comprising a frame having a movably mounted top bar carrying pressure screws, U-shaped members unbracing the side bars of said frame at their upper ends, said U-shaped members being provided with oppositely disposed hooks, and a bowed spring formed of a piece of wire having enlarged loop portions at its ends adapted. to be arran ed under said hooks for holding said top bar in position within said wringer frame.

271K clothes wringer comprising a frame having slotted side bars, a top bar slidably mounted within the slots of said side bars, pressure screws carried by said top bar, U- shaped members embracing the side bars of said wri'nger frame attheir upper ends, the upper edges of said U-shaped members being provided with oppositely disposed hooks, bearings secured on the top bar to one side of said hooks, and a bowed spring formed of a piece of wire having cross bars at its ends arranged under said books on said bearing plates for normally holding said cross bar in position within said wringer frame.

3. In a wringer, the combination with a pressure roll and pressure means therefor, of a top bar slidably mountedwithin said wringer frame having pressurescrews for adjusting said pressure means, a bowed spring formed of a piece of wire having enlarged portions to form cross bars at its ends carried by said top bar, and hooks carried by the side bars of said frame adapted to receive the cross bars of said bowed spring for preventing upward movement of thetop bar thereof.

4. In a clothes wringen, the combination with a frame having pressure rolls and pressure means mounted therein, of a top bar slidably mounted within said frame having pressure screws for adjusting said pressure means, U-shaped members embracing the side bars of said frame at their upper ends, the upper edges of said U-shaped members being provided with oppositely disposed hooks, bearing plates secured on the upper face of said top bar to one side of the said books, a bowed spring formed of a single piece of wire having cross bars at its ends arranged under said hooks, and resting upon the bearing plates of said top bar for normally holding said top bar in position with said frame. I

5. A clothes wringercomprising a frame having pressure rolls and pressure means mounted therein, a top bar movably'mounted within said frame having pressure screws, oppositely disposed hooks carried by the side bars of said frame and extending upwardly in a plane above the top bar and a bowed spring formed of a single piece of wire bent into loop form to provide cross bars'at its ends arranged under said hooked portions over said top bar for preventing upward movement of said top bar, said cross bar being adapted to be forced out from under said hooks by exerting a downward pressure upon said spring.

In testimony whereof I hereunto afi'ix my signature in the presence of two witnesses.

JOHN HEMENWVAY.
